FOLDING VI OLIN-BOW.

To all whom it may concern Be it known that I, JOHN D. ADAMS, a citizen of the United States, and a resident of Phoenix, in the county of Maricopa, State of Arizona, have invented a new and useful Improvement in Folding Violin- Bows, of which the following is a specification.

My invention is an improvement in folding violin bows for violins and has for its object the provision of means in connection with the bow for permitting the bow to be folded into small compass for convenience in carriage, and so arranged that when un folded into playing position the hair may be properly tensioned and will be held in such condition.

In the drawings: Figure 1 is a side view of one end of the bow, showing the bow unfolded; Fig. 2 is a similar View, showing the method of folding; Fig. 3 is a longitudinal section of a part of the bow unfolded; Fig. 4 is a view similar to Fig. 3, showing a modification; Figs. 5 and 6 are partial longitudinal sections of other modifications; and Figs. 7 and 8 are side and plan views, respectively, of another modification.

As is known, the bow is of greater length than the violin, and as a consequence the storage and carriage of the instrumentnecessitates a long, unwieldy and ugly case, usually coffin shape, and having at one end of the violin portion of the case a block or useless compartment to compensate for the additional length of the bow.

With the present invention the instrument may be carried in a rectangular case of approximately the same length as the violin. The joint is preferably at the end of the bow provided with the frog, although it is obvious that it might be at the other end.

In the embodiment of the invention shown in Figs. 1 and 2 the bow is divided adjacent to the frog 2 into two sections 1 and 1, and at a point such that the longer end of the bow is approximately equal to the length of the violin. The inner end of one section, the section 1 in the present instance, is provided with spaced lugs 3, and the inner end of the other section 1 is provided with a lug 4 received between the lugs 3 and pivoted thereto by a pivot pin 5. V or headed at each end, and the corners of the lugs 3 and 4 at one side are rounded, as indicated at 6 (Fig. 2) to permit the sections to be folded in one direction. The lugs 3 Specification of Letters Patent.

and 4 are formed on the ends of sockets 7 and 8, respectively, and the said sockets are fitted onto the inner ends of the sections (Fig. 3). Each of the sections 1 and 1 is reduced at its inner end to receive the sockets, so that the outer surface of the sockets is flush with the outer surface of the sections, and the outer endof socket 8 is beaded, as indicated at 9. A ferrule 10 is slidably mounted on the sections and is movable over and away from over the joint to lock the sections in alinement. of the ferrule is beaded, as shown at 11, and in the present instance the socket is limited in its movement toward the frog by the head 9 of the socket 8. l/Vhen the bow is to be folded, the ferrule is moved away from the frog, until the joint is uncovered. The section 1 may then be turned at right angles to the section 1, and when in the case with the violin the said section may lie across the neck.

In the embodiment shown in Fig. 4t the sockets 7 and 8 are replaced by sockets 12 and 13, respectively, and the socket 13 is of greater length than socket 8, the joint being at a greater distance from the frog. The said sockets are provided with beads 11 and 15 respectively, and a ferrule 16, provided at each end with a bead 17, is slidable on the sockets. The socket 13 is provided with spaced lugs 18, and the socket 12 with a single lug 19 received between the lugs, and pivoted thereto by a pin 20. The ferrule 16 slides toward the frog 2 to uncover the joint and moves at all times on the sockets, being limited by the beads 14 and 15.

In Fig. 5 a socket 21 is provided for one section, having three spaced lugs 22, and the socket 23 for the other section is provided with two lugs 24 received between the lugs 22 and pivoted thereto by a pin 25. In Fig.

6 each socket 26 and 27 is provided with a lug 28, and the lugs lap alongside each other and are connected by a pin 29.

In each of the above embodiments the sections may take a position at right angles to each other, but are not capable of folding into parallelism. The embodiment shown in Figs. 7 and 8 is designed to permit the sections to fold upon each other.

In Figs. 7 and 8 each of the sockets 30 and 31 is provided with spaced lugs 32. A link 33 is arranged between the sockets, one end of the link being received'between one pair of lugs, and the other end between the Each end other pair. A pin 84 is passed through each pair of lugs and the link. The ends of the lugs are rounded on an are having its center at the adjacent pin, and one corner at each end of the link is also rounded. When the sections are in alineinent the ferrule (not shown) entirely conceals the joint, as it does in all of the forms. To fold the how it is only necessary to slip the ferrule in the proper direction to uncover the joint, and to aline the sections the ferrule is slipped in the opposite direction. The construction shown in Figs. 7 and 8 permits the sections to be folded onto each other. It Will be noted that the hinge is at the point occupied by the usual grip, that is, the ferrule takes the place of the grip, acting both as a grip and as a concealing device for the hinge. The delicate balance of the boW is thus not interfered With.

rule When in locked position being adjacent t0 the frog and acting as a grip.

2. A violin bow divided into sections at a point adjacent to the frog, a hinge connection between the adjacent ends of the sections, a ferrule slidable over the joint for locking the sections in alineinent, said ferrule When in looking position being adjacent to the frog to act as a who for the bow.
